Bash does not configure in job control when cross-compiling. You can remove the JOB_CONTROL_MISSING define from config.h and try building without it, but there's no guarantee that the necessary capabilities are present on the target system. The macro you partially quoted above encapsulates the required functionality. If building without JOB_CONTROL_MISSING defined doesn't result in a binary with job control working, the tests in the macro give you a hint about where to look. Chet removing JOB_CONTROL_MISSING from config.h doesnt work. but when i do: export bash_cv_job_control_missing=present job control is compiling and working. Chris

cross-compiling bash is known to be broken as it'll mix your host signal defs into the target binary This is no longer true; bash-3.2 builds the signal list at invocation time rather than compile time when cross-compiling.
